To all whomit may concern Be it knownzthatII, I'IENRY V SCHMIDT, a citizen of the United.Statespand resident of Johnstown, in the .eount'y of Cambria andState of Pennsylvania,have in vented certain new and useful jlmprovements in AdjustableWheels an'dAXles'ot' which the following .is a specification;

This invention'iis an adjustable mounting for car wheels, 'Ewhereby the wheelsfinay be set to any desired Egageon theaxle;

Important advantages of the invention; are to obtain uny desired adjustments zwith out removing the 'Wheels" fronrthe a;Xle"and; withoilt removing axles from 1 the trucks :to

obviate the "use of threads 'on theaXles a's have hitherto been used; to facilitate the adjustable shifting oft'he Wheel onthe axle; and to maintam a rigldeonneetion between the Wheel and'the axle so that 'tlie wheelinay rotate with the axle. lVith these andother objeotsin view, the

present invention consists in the combin'ation and arrangement of parts as will behereing artter more fully described;illustrated n the accompanying *drawings "and particularly ponited out 111 the appended -el:'mns',-1t of course: being 'un'd erstood that changes V in the form, proportion; slze and ininoridetails may. be made, Within the scope of 'the elai'm's,

' lsae'rifie ing any of the advantages 0 the invention! I r 'jb'e hereinafterdescribed.

The axle I is provided ateaehiend with a V cylindrical seat portionflyon "whieh 'any' or; 5 dinary or preferred rforiu-"of ;Wl1el'.:i mounted, said wheel having a hub't 'wlneh F. A; FKLEIN islreyedto the seat portion of the axlehy means of asnitablekeyt. At the inner end offthe seat there is an integral annular shoulder '6, and adjacent the outer end of {these'at there is an annular groove 7; At tlieouter side of the seat there is the usual spindle portion 8 designed to rotate'within' aijour-mil: box in the usual manner. Asbest shownin Fig.5. of the drawings, it will be seentliatrtlie Wheel seat 2 of theaxl'e is pro- "vlded zwith a keyway 9 to receive the key 5;

andns indi'eated inFigs. 1 2 and 3 it will be seen-that this keyway extends throughout tlie,=.len'gtl1 ot the Wheel-sezt Q, being closed atzits inner; end by the annular shoulder 2 andbpen at its. outer end to permit of the ready introduction and removal of the key;

' Cooperating with the annular groove 7 1s a" removable and reversible shoulder or abutment made up of dnplicateseetions 10;

each seetion being provided: at its inner edge the size-and shape to fit snugly the groove 7 0i the-axle. The outer :Eaeeof thisrrib is flush-With one oi the outer faces ofzthe abutmenhseetion '10; :nnd the width ofthe ribis slightly less than one-half that orf'the abutmentsection, Wherefore said rib 11' is; offset: .WltlXIQSPQOt to the longitudinaleen':

tero'flthe:abutmentgfor a purpose as will" abutment section are .enlarged or provided w th the 'I'GSPGC'tlVB'bOSSBS '12 and 13, and

thesexb'osses-are provided with the parallel bolti'openings 14 and lo respeetively. Two

suehifabutment segments or seetion'sare ap- 'plieditothe Wheel seat 2' of the axle, as best shown, in Fig. dot the drawings, and are" each abutment section 10, and t 1e registered groovesofthe two sections.eonstitute a key .itj to accommodate the key 5. Asbest shown in- -Figi 7, it will beseen that the key" 5,:is provided upon :one face with'transverse notohesorseats 19, oneo'r the other iotwhich isldesigned to aeeonnnodate the bolt 17,5a'ecordingito the position of the removable 'dra' win gs. When the: removabl e abutment is thusfit'ted -in place, it is held against met-ement endwise ofthe axle by the interfitting of the rib 11 in the groove 7, and is pre- .seat or'recess 31in the adjacentiace of the vented from rotating upon the axle by reason of the key 5. Moreoverthe bolt 17 holds the key 5 in place and prevents endwise displacement thereof.

The distance between the fixed shoulder or abutment 6 and the removable abutment 10 exceeds the length of the hub 4 of the wheel, and in order that the hub of the wheel may be held firmly between the two abutments there is provided suitable wedglng means which maybe interposed between either of the" abutments and the adjacent end of the wheelhub. This wedging means includes a collar made up of substantially duplicate sections 20 and 21, each ofwhich is provided with a semicylindricalopening that corresponding faces 28 of the wedge sections are straight and lie in the same plane, while the opposite faces 29 of said wedge sections incline inwardly from the outer edges to the inner edges thereof thereby giving each wedge section a tapered or wedge shaped cross section. 1 ,One of the wedge sections is provided upon its inner edge with a transverse groove 30, shown'in Fig. v5 of the drawings and constituting a keyway to accommodate the key 5, whereby the wedge element is held against rotation upon the axle. The inclined or wedge face 29 of the wedge member 21 is provided with a recess or seat 31 in alinement with thekeyway 30 for a purpose as will be later ex-i plained. Interposed between the wedge ele-' ment and the adjacent end of the wheel hub there is a filler or washerelement made up oftwo semicylindrical sections 32 and 33, one of which has been shown in detail in Fig. 6 of the drawings. As clearly shown in Figs. 1 and 2 of thedrawings, the face 34 of each washer or filler section is disposed in aplane at right angles to the axis of the section so that these two straight portions may lie flat against the adjacent end of the wheel hub. The opposite face 35 of the washer or filler section is inclined so as to correspond with and fit directly against the inclined face 29 of the adjacent wedge element 28, whereby, upon tightening the nuts on the bolts 26 and 27 the wheel hub will be crowded snugly against the opposite abutment and thereby effectually held in place against movement longitudinally of the axle. The washer or. filler section 33 is provided with akeyway 36 to accommodate the key5. Upon the wedge or inclined face havin adjacent wedge section 21, thereby to pre vent rotation of the filler section and insuring the properassemblage of the several parts.

The fixed abutments 6, only one of which has been shown, are spaced according to the standard gage of tracks,so that when the;

hub of the wheel isagainst the'fixed abutment 6, as shown in Fig. '1 of the drawings,

the wheel is set for standard gage. When the wheel is thus set, the removable abutmentlO is disposedso as to lap the wheel seat 2, and the wedge and filler element are interposed between the outer end of they wheel hub and the removable abutment.

By referring to Fig.2 of the drawings,

it will be seen that the wheel may be shifted to an intermediate pos1tion,'without removing'the removable abutment 1,0, merely by 1.:e1noving the wedge and l fillerfelements shifting the wheel over against the removable abutment 10, and replacing the wedge element and the filler element at the opposite side of the wheel between the fixed abutthe abutment laps 'theseat' portion 2. at the outer side of the groove7. This disposition of the removable [abutment of course increases the space between the inner end of the hub and the wedge element, andto take care of this relation of parts, there is provided a 'fille'r'elem'ent 38 of the necessary,-

thic'kness. a a Y By providing filler elements of difierent thicknesses, any desired intermediate adjust ments of the wheel may be obtained. What Iclaimisz l.
